Question

Six equal resistances are connected between points P, Q and R as shown in the figure. Then the net resistance will be maximum between

  1. P and Q    
  2. Qand R    
  3. P and R    
  4. Only two points    

The correct answer is: P and Q


    R subscript P Q end subscript equals fraction numerator 5 over denominator 11 end fraction r comma blank R subscript Q R end subscript equals fraction numerator 4 over denominator 11 end fraction r a n d R subscript P R end subscript equals fraction numerator 3 over denominator 11 end fraction r
    therefore R subscript P Q end subscriptis maximum.
